I use Firefox 134.0.2 (64-bit) on Ubuntu 24.04.

Some (not all) web sites show up only after a delay of exactly 30 seconds. The attached screenshot shows that this delay is due to DNS resolution. This behavior is reproducible by simply closing Firefox, opening it again and entering the same web site once more. Once this initial delay of 30 seconds for DNS resolving has passed the web site can be browsed normally.

Using Google Chrome, Opera or even the Tor Browser on the same system works without any significant delay. Also a DNS lookup from the console returns data almost immediately.

As the delay is always exactly 30 seconds this looks like some DNS resolver timeout only showing up when using Firefox.

Neither starting Firefox in Troubleshoot Mode nor (as often suggested) disabling IPV6 for DNS by setting network.dns.disableIPv6 to true did help.

Any idea how to fix this 30 seconds delay?

Many thanks for any help, Felix

I've used Firefox for many years. The past month or so weather radar doesn't come up on multiple weather sites, pages are slow to load or don't load, getting error codes on video's, pictures don't always load, and many other problems. I uninstalled Firefox and re-installed the current browser and I still have all these problems. I'm having to use another browser now. I run Windows 11 on my PC.

I downloaded a PDF and used Firefox to view the file. I'm trying to find key words in the PDF and I always get phrase not found. As a test I inputted a word I found in the document but find in page stated phrase not found. What am I doing wrong? I remember that I have used that feature in the past and it worked.

I realy hope you can solve those issues. Kind Regads! Gina Monica Ciuca

my new monitor offers a screen where I can shut down, sleep, or restart.......I usually chose sleep, because I think it allows me quicker access to my browzer home page when moving the mouse for reboot. However, about six or more times now, the sleep mode will stop, a "don't interrupt" message in ghost script in the upper left hand corner of the screen comes on, the an HP logo with a dizzing circular moving gif suggest the computer is starting........no so. I have waited 30 minutes or more, started and stopped with the power button, hit every key on the board and swear prolifically now and then with NO results.

Using a fairly new HP computer, win 11, and version 134.0.2 of FireFox......AND, I'm a good guy. I think so, anyway. What am I doing wrong. It seems that each time this happens, if and when the computer will restart, that FireFox has an update in the wings and needs to have that installed before I move on to use the pc. Is there a connection?

Hello,

I use Screen Time to block sites on my Mac, running Sequoia 15.1.1. For some reason, it recently (within the last 2 weeks or so) stopped blocking sites on Firefox 134.0.2, but not on Safari.

Is this a known issue? Is there a solution?

Thank you for your help.

I have been messing with my computer and this morning Firefox had ceased to function, and I will be looking for my extensive bookmark list here or on another drive.. I just feel that windows 11 is pernicious!!
